C4C0 No motor
current %s
Motor connected incorrectly or not at all
Inverter defective
Motor defective
Incorrect motor selected in motor table
Motor power cables crossed
Check the motor and wiring.
Check the inverter.
Conductor bars not tightened sufficiently Tighten the conductor bars securely.

Motors.
C5F0 Wrong
position-encod.
input
An incorrect input was selected for the position
encoder (MP110.x/MP111.x)
Possible configurations:
CC 4xx/6 control loops: X201 to X206
CC 4xx/8 control loops: X201 to X208
CC 4xx/10 control loops::
PWM outputs X51 to X56: X201 to X206
PWM outputs X57 to X60: X207 to X210
Check MP110.x/MP111.x.
E170 Position
error too large
<axis>
Parameter value in MP640.x is too small
Defect in the mounting of the position encoder
Incorrect temperature compensation, or linear
or nonlinear compensation
Excessive backlash
Check the parameter value in MP640.x
(maximum position deviation between
MC and CC during operation).
Check the parameter value in MP720.x (linear
axis error compensation for analog axes).
Check the parameter value in MP710.x
(backlash compensation).
Check the mounting of the position encoder.
See ”Sequence for finding errors in the control
loop” on page 6 – 58.
F010 DSP error in
axis %.2s
Error in the power stage of the displayed axis Inform your service agency.
Axis <axis> motor
current not equal
to 0
The axis motor is receiving current, although its
inverter was switched off!
Inform your service agency.
Switch-off pos.
%.2s unequal
ENDAT
Last saved axis position does not correspond to
the current position of the rotary encoder with
EnDat interface.
Check MP960.
Inform your service agency.
See ”Encoder interface” on page 19 – 277. See ”Encoder interface” on page 19 – 277.
Operating
parameters
erased
The machine parameters have been erased and
the PLC program is missing.
Enter new operating parameters.
See ”Restoring data” on page 14 – 207.
Movement
m
onitoring error in
<axis> A
The axis is moving at least 4 times slower or
faster than commanded by the nominal speed
command output.
Large backlash
Overloaded driver
Insufficient lubrication
Mechanical stiffness
Machine vibration
For analog axes: Servo defective
Check machine parameter MP1140.x.
Remove any large backlash.
Check the lubrication.
Remove mechanical stiffness.
Analog axes: Check the servo.
Inform your service agency.
See ”Sequence for finding errors in the control
loop” on page 6 – 58.
